Bernoulli equation and the nonexistence of maximal jets

, 2015
We discuss the idea of maximal jets introduced by Falcke & Biermann in 1995. According to it, the maximum possible jet power in its internal energy equals the kinetic power in its rest mass.

Optical Solitons Possessing Beta Derivative of the Chen-Lee-Liu Equation in Optical Fibers

Frontiers in Physics, 2019
This research obtains some new optical soliton solutions with beta derivative for Chen-Lee-Liu equation (CLL) in optical fibers. Three integration schemes which are Ricatti-Bernoulli (RB) sub-ODE, generalized Bernoulli (GB) sub-ODE and generalized tanh ...

Fractional pure birth processes

, 2009
We consider a fractional version of the classical nonlinear birth process of which the Yule--Furry model is a particular case. Fractionality is obtained by replacing the first order time derivative in the difference-differential equations which govern ...

Phantom Accretion onto the Schwarzschild de-Sitter Black Hole

, 2011
We deal with phantom energy accretion onto the Schwarzschild de-Sitter black hole. The energy flux conservation, relativistic Bernoulli equation and mass flux conservation equation are formulated to discuss the phantom accretion.

Diophantine equations with Bernoulli polynomials [PDF]

Acta Arithmetica, 2005
The authors consider the equation \[ aB_m(x)=bB_n(y)+C(y), \] where \(C(y)\in\mathbb{Q}[y]\) and \(m\geq n>\text{deg}\;C+2\). Applying the method of \textit{Y. F. Bilu} and \textit{R. F. Tichy} [Acta Arith. 95, No.~3, 261--288 (2000; Zbl 0958.11049)] they show that this equation has only finitely many rational solutions \((x,y)\) with bounded ...

Extended Bernoulli equation, friction loss, and friction coefficient for microscopic Jeffery-Hamel flow with small Reynolds number up to O(1)

Journal of Fluid Science and Technology, 2016
The extended Bernoulli equation is formulated in an exact form for a microscopic and small Reynolds number Jeffery-Hamel flow in a two-dimensional convergent or divergent channel.

Carleman estimate for an adjoint of a damped beam equation and an application to null controllability [PDF]

, 1886
In this article we consider a control problem of a linear Euler-Bernoulli damped beam equation with potential in dimension one with periodic boundary conditions. We derive a new Carleman estimate for an adjoint of the equation under consideration.

Solutions of the Perturbed KDV Equation for Convecting Fluids by Factorizations

, 2009
In this paper, we obtain some new explicit travelling wave solutions of the perturbed KdV equation through recent factorization techniques that can be performed when the coefficients of the equation fulfill a certain condition. The solutions are obtained
